The Rough Country website says the kit won't fit "AWD Models" and the Quadra-Drive system possesses a 4-All Time option, as well as Neutral and 4-Lo. The NV247 transfer case used by the Quadra-Drive system is the same as the Quadra-Trac II, which has the option for 4-Lo, Neutral, and 2wd, right? The only other option is the Quadra-Trac I which doesn't have 4-Lo or Neutral (NV147 transfer case).

I saw that remark about the awd on rough country's site too. I am still debating on 3 or 4 inches but mostly it depends on if I can get it in and out of the garage door openning is only 78 inches high. Don't see what the problem would be everyone else that offers 4 inch kits don't have that statement.

the only reason they say to not lift awd jeep is because if you have warn u-joint in the front driveshaft, of your pinion angle isn't as good as it should be, your more prone to get vibrations that you wouldn't of at stock height.

right now i am waiting for adjustable front upper control arms to ship, but in 2wd i have no vibrations except for deceleration vibrations, but i have a bad vibration in either 4by mode.

This is the setup I ran. I have since swapped out my transfer case with a 242. The quadra drive and quadra trac II are the exact same TC, both with 4wd, N, and 4-low. The only difference between the two systems is the quadra drive comes with vari-loc diffs front and rear, while the quadra trac II has open diffs.

There is absolutely no reason why it wouldnt "fit." The suspension geometry is exactly the same between models with a 247 TC and a 242 TC. The only issue you MIGHT have is that your front pinion angle may be too far off causing some drive line vibes (I dont have this issue, but some people do.) Some adjustable front upper control arms will fix that and no 4" kit on the market comes with adj front uppers. There is nothing in this kit that would make it "not fit" that is different than any other 4" kit on the market. In fact, this is one of the few kits (if not the only kit) that comes standard with an adjustable track bar and adjustable front lower CAs.

It is by far the best bang for your buck, especially if you order it through casanova4x4. Shoot him a PM and see what kind of discount he can get you. I got my kit from him, with a new steering stabilizer, shipped to my door for under $700.

I have a RCX 4" on my 04 WJ. no issues . you will just need to replace the front DS sometime later. I have the 247 tcase and no issues. i didn't think the 147 was in anything but WKs. recon this a bit and get back with me. I am curious now.

actually you can get the 147 transfer case in a WJ. I found some that had the trail rated badge but there is no shifter in the console but there is a front axle. The reason there is no shifter is because it is a single speed auto transfer case. It is like the 247 without the 4-low gear range. Jeep Grand Cherokee WJ - WJ Four-Wheel Drive Systems

you have the same question I had so while I was at the rough country website I clicked on the live chat tab at the top of the page and asked why it wouldnt fit and they said that it will fit but it MAY vibrate while driving and he said I could buy different drive shafts to correct the vibration. and I plan on buying a wj soon and am going to be buying this lift kit and if it does vibrate than I will look for the right drive shafts.
